BEATING AND MIXING MACHINE FOR CONFECTIONERS U SE.

SPECIFICATION forming part of Letters Patent No. 561,298, dated June 2,1896.

Application filed January 13, 1896. Serial No. 575,862. (No model.)

T0 11 whom it nuty concern: I

Be it known that I, JOHN l/VERNER, of Rochester, in the county of Monroeand State of New York, have invented a certain new and usefulImprovement in Beating and Mixing Machines for Confectioners Use; and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the drawingsaccompanying this application. My improvement relates to syrup beatingand mixing machines in which spirally-ribbed rollers force the syrupforward through a casing.

The invention consists in the construction and arrangement of partshereinafter described and claimed.

In the drawings, Figure l is a plan view of the machine with the topplate removed. Fig. 2 is a longitudinal vertical section of the same inline new of Fig. 1. Fig. 3 is an enlarged crosssection in line 3 g ofFig. 2. Fig. 4 is Fig. 5 is a 1ongitudinal vertical section of one ofthe journal-bearings.

A A indicate a four-chambered casing, in which are located fourspirally-ribbed rollers B B and B B, two above and two below, with apartition a separating them. The rollers are so disposed that the twoupper ones B B feed the syrup forward from the entrance'spout h to theopposite end of the machine, where it falls through an opening 0 in thecentral partition, and is then fed back in the reverse direction by therollers B B, and is finally discharged at the exit-spout d into asuitable receptacle. The journals of the rollers extend through the endsof the casing and are driven by a set of gears 1 2 3 4 5 6, so arrangedthat the two lower rollers B B run faster than the upper ones, therebyal ways insuring a free discharge and prevent ing any clogging.

Each of the rollers is made in sections f f f by turning V-shapedgrooves at intervals in the roller down as deep as the spiral ribs 9 g,or deeper, and in these grooves rest V shaped flanges h h of the casing,fitting closely therein. The flanges extend only half-way round and restin the lower half of the grooves, thereby leaving the top surface of therollers entirely open and forming a passage-way for the syrup over thetop of the rollers from end to end of the machine. ting in the lowerhalf of the grooves effectually cut off the passage of the syrup underthe rollers, forming stops and causing the spiral ribs of the rollers toforce it to the top. The spiral ribs incline outward and upward, wherebythe tendency is to carry the syrup toward the center, thus facilitatingits passage and thoroughly grinding it up.

K Kare two independent heads of the two upper rollers, located at thedischarge end, or the end away from the feed-spout, and provided withspiral ribs standing at the reverse incline from those on the sectionsff of the rollers. A space I is left between these heads and thesections ff, which space comes over the dischargeopening c. The objectof these independent heads is to oppose the current of syrup passingthrough the upper chambers and force it back, so that it will dischargethrough the opening 0, and also to prevent the passage of the syrupoutward around the journals of the rollers through the casing, which ittends to. do under the great pressure to which it is subjected. Similarindependent heads K K are located at the discharge end of the lowerrollers fora similar purpose-Vin, to force the syrup down into theexit-spout d and to prevent the syrup passing through thejournal-openings.

m m are the journal-bearings at opposite ends of the machine, eachholding the ends of the journals. These bearings are located away fromthe ends of the case, as shown, so as to leave a clear space between theends of the case and the bearings, the journals being uncovered in thatspace. The boxes are provided with oilholes, and beneath the boxes aredischarge-passages n 71, extending through the bearings longitudinally,by which means such oil as drips down is discharged at the end. By themeans above described no oil is passed inward through the end of thecase to come in contact with the syrup.

The machine can be made effective with only one pair of rollers, thecase in that instance being single instead of double and thedischarge-spout at being placed at the point where the opening o islocated.

The flanges by fit- Having described my invention, what I claim as new,and desire to secure by Letters Patent, is'

1. In a syrup-mixing machine, the combination of a pair ofspirally-ribbed rollers, provided at intervals with circumferentialgrooves, and a case containing the rollers provided with flanges restingin the lower part of said grooves and extending but partially around therollers, leaving the top of the rollers uncovered, as and for thepurpose specified.

2. In a syrup-mixing machine, the combination of two pairs ofspirally-ribbed rollers provided at intervals with circumferentialgrooves, and a case containing the rollers, said case provided with apartition separating the pairs of rollers, and with flanges resting inthe lower part of the grooves and extending but partially around therollers, leaving the top of the rollers uncovered, as and for thepurpose specified.

3. In a syrup-mixing machine, the combination of a case, a pair ofspirally-ribbed rollers resting in the case, and heads at one end of therollers separated therefrom by an intervening space, said heads providedwith spiral ribs standing reversely to those on the rollers, as and forthe purpose specified.

In Witness whereof I have hereunto signed my name in the presence of twosubscribing Witnesses.

JOHN WERNER.
